In this paper, the continuous motion of a quadrupedal walking machine was studied. The motion planning which is able a walking machine body to precisely follow a three-dimensional curve was developed. A three-dimensional curve was designed based on Bezier curve and obstacle avoidance considerations. Due to the arbitrary motion direction during walking, special strategies of gaits were developed to ensure positive stability. The gait strategies were based on wave and wave-crab gait.

This paper presents a novel method of path planning for a quadruped walking robot on irregular terrain. In the previous study on the path planning problem of mobile robots, it has been usually focused on the collision-free path planning for wheeled robots. The path planning problem of legged roboth, however, has unique aspects from the point of viw that the legged robot can cross over the obstacles and the gait constraint should be considered in the process of planning a path. To resolve this unique problem systematically, a new concept of the artificial intensity field of light is numerically constructed over the configuration space of the robot including the transformed obstacles and a feasible path is sought in the field. Also, the efficiency of the proposed method is shown by various simulation results.
